NARCAO_LOC_SU_TERRAZZU Wastewater Treatment Plant, Narcao, Sardinia

NARCAO_LOC_SU_TERRAZZU is an advanced wastewater treatment plant located in Narcao, within the Sulcis Iglesiente area of Sardinia, Italy. The plant serves a population of approximately 2,253 residents, providing essential sanitation services to this small community. It operates under Italy's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets standards for collection and treatment of wastewater. The plant employs advanced treatment processes, going beyond the secondary treatment required by the EU directive for agglomerations of this size. With a designed capacity of 2,378 cubic meters per day and a current discharge volume of about 446 cubic meters per day, the facility has ample capacity to handle current loads. The advanced treatment ensures high-quality effluent, reducing nutrients and pollutants before discharge. The treated wastewater is released into the local watershed, which ultimately drains into the Mediterranean Sea. This is significant because Sardinia's coastal and marine environments are ecologically sensitive, supporting diverse aquatic life and tourism. By providing advanced treatment, the plant helps protect downstream water quality and the region's natural resources.

The plant discharges into the local watershed in the Sulcis Iglesiente region, which flows into the Mediterranean Sea. This coastal area supports important marine habitats and is a key resource for local communities and tourism. Advanced treatment helps minimize nutrient loading and protects the sensitive coastal ecosystem from eutrophication and pollution.
